Operator TriMet relies on rail technology from Siemens for newly opened light rail line

14.09.2015
  • MAX Orange Line between Portland and Milwaukie
  • 18 light rail vehicles S70 type energy
  • Energy storage system type Sitras SES
  • Signaling and communication system

Today, TriMet's new MAX Orange Line, a light rail project between Portland and Milwaukie (USA), was officially inaugurated. Siemens advanced rail technologies are now operating on the Orange line including its S70 light rail vehicles designed and manufactured at Siemens Sacramento, California plant to move riders along the system, rail signaling and communication systems to help manage train operation, and the company's first Sitras SES energy storage unit in the U.S. that uses regenerative braking to sustainably power the line.


The 7.3-mile (around 12 Kilometer) MAX Orange Line is the region's sixth construction project of the development project Metropolitan Area Express (MAX) to expand the city's transport network to cope with the expected population growth in the Portland area. The line will improve transit in the corridor that extends from the terminus of the MAX Green and Yellow lines at Portland State University in Downtown Portland to Milwaukie and North Clackamas County.

"Siemens is proud to be a technology partner for Trimet for more than 30 years, starting in the this project is a perfect example of how advanced rail technologies can help to revitalize city centers, creating jobs and stimulating economic development", said Jochen Eickholt, CEO Siemens Mobility Division.

The newly redesigned light rail vehicles were built based on input from TriMet and riders, featuring new seating arrangements, additional wheelchair accessibility, larger windows and improved HVAC systems that automatically adjust based on the number of people in the vehicle.

The vehicles also include better sight lines for the driver, more ergonomically designed main cabins, and larger displays for train operators so they are better able to monitor the vehicle's status to improve safety and efficiency. Maintenance enhancements were made based on TriMet's feedback including rearrangement of systems to increase accessibility to key components on the vehicles and improved diagnostic systems.

The innovative regenerative rail energy storage technology allows for energy created during braking to be stored and then re-used in one of two forms, energy savings or voltage stabilization during peak demand times. TriMet will utilize the system in voltage stabilization mode. In this mode, the storage unit allows the system to avoid problems disruptions that can occur in mass transit operations if power drops below a certain level.

If a number of vehicles accelerate simultaneously, system voltage can drop below a critical level and result in instances of under-voltage tripping in vehicles and, consequently, lead to disruptions in passenger service. The Sitras SES ensures the system voltage always remains within the required range and voltage-related disruptions no longer occur.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
